Post Disaster Relief Operations Communication Using Grid Location Services in Smartphone

During any large-scale disasters like flood and cyclone have severe impact on communication Infrastructure. The availability of the Internet is ruled out in this case, mobile phones are not fully usable in some selected regions. Devices for maintaining minimal services are mostly expensive satellite phones or specialized point to point radio communication systems. One of the major problems during disasters is that the rescue and relief operations are not coordinated well. For this reason, there is a need of system that will help in the efficient distribution of rescue and relief to disaster-affected areas. In contrast to the vulnerable fixed network infrastructure, it is very likely that battery powered wireless personal mobile communication devices will survive in disasters. Currently, those devices are having powerful processors and high storage capacity with GPS and multi radio interfaces. Such devices are therefore, promising candidates to contribute in forming peer-to-peer wireless network structure to support disaster communication. Mobile nodes communicate with each other in peer to peer mode. At the same time the mobile volunteers also exchange information among one another in a peer to peer mode, thus integrating field information intelligently and autonomously using auto configurable mobile-phone-based peer to peer communication.
